IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 184,803, dated November28, 1876; application filed October 4, 1876.

To all whom it may concern Be it known that I, CHARLES W. SoULE, of thecity of Boston, county of Suffolk, and State of Massachusetts, haveinvented a new and useful device, it being an Improvement inLamp-Burners; and I hereby declare that the following specification,taken in connection with the drawings, is a true and completedescription of making and operating the same.

This improvement consists of a device for operating a cylindrical wickwithin a tube or receptacle for oil or other illuminating fluids,

and also. to have said receptacle tightly closed,

except where the wick emerges at the top. The receptacle is formed bytwo cylinders of metal, the bottom closed, so as to make a tight vessel,the wick being inserted between said cylinders.

In Figure 1 is shown said tube or receptacle in perspective. Fig. 2 is asection of the same at or near the ratchet-wheels, showing saidratchet-wheels, inner tube, and the cor-. rugated or toothed portion ofthe same. Fig, 3 shows the upper portion of the tube with ratchet-wheelsuncovered. Fig. 4 represents a longitudinal section, showing a false ordouble tube in the upper portion thereof, the outer periphery of whichis corrugated. The lower portion of Fig. 4 shows continuation ofreceptacle and false tube, to which latter a dripcup is attached. Figs.5 and 6 represent ratchetwheels.

Like letters in the different figures denote like'parts of the device. I

In Figs. 1, 2, 3, and 4 is shown the cap A, tightly fitting upon theouter circumference of the receptacle F. In Fig. 2 is represented theratchet-wheels B, inserted through slot-s from the outer cylinder F, andnearly touching the flanged portion of the false tube 0, which iscorrugated or fluted at that point op! posite, and to conform to saidratchet-wheels.

In Fig. 3 are shown the slots E E, perforated obliquely through theouter cylinder F. In

Fig. 4 is represented the inner cylinder of the receptacle 9 g, and H isthe drip-cup, attached to-the false tube 0, which has a flanged ordouble top turning downward, shutting over the inner tube within thereceptacle F to where the toothed portion of said false tube meets theratchet-wheels B, and forms a gear for passage of a wick between.

The false tube 0, upon which the wick is placed, presses the wick firmlyagainst, and meshes the same into, both the fluted portion of the falsetube and the toothed ratchetwheels B.

Slots are pierced through the outer cylinder F, and the ratchet-wheels Bare inserted through and upon said cylinder at an angle of thirtydegrees, more or less, as desired.

To operate this device, turn the drip-cup H, attached to the false tube0, to the right, which turns the false tube, carrying with it the wick,the latter revolving and meshing into said false tube and ratchets. Thelatter, turning obliquely, raises said wick to any re- .quired height,and, by turning the cup to the left, lowers the wick by reversemovement.

What I claim as new, and desire to secure by Letters Patent, is-- l. Theratchet wheels inserted obliquely through the outer cylinder F, tooperate a cylindrical wick within a tube or oil-receptacle,substantially as described.

2. In combination with the ratchet-wheels B, the tube 0, folding overand covering the surface of the inner cylinder g,'said tube beingcorrugated opposite the said ratchet- Wheels, asset forth.
